IPC: B65H3/08
Abstract: 134,908. Forrester, H. J. C., (Miehle Printing Press & Manufacturing Co.). Nov. 11, 1918. Sheet-separators. - In a sheetbuckling device for separating the top sheet of a pile, the corner of the sheet is lifted by a suction device, having a mouth of concave section transversely, which is then moved diagonally towards the centre of the sheet to buckle the sheet downwards. Two lifting suckers may be used, the outer one moving diagonally towards the other. Separating-blasts and holding-devices are provided in conjunction with the buckler. As shown in Figs. 3 to 7, two buckling nozzles 25, 30 are provided over the corner of the pile 12 on a table 11, the upper sheets 15 being loosened as shown in Fig. 4 by blasts of air from nozzles 13, 14 and then lifted by the nozzles 25, 30, which are carried by a vertical slide 20 operated by a cam. The mouth 25<a> of the nozzle 25 is concave transversely so as to bend the outer corner 12a of the sheet downwards as shown in Fig. 6. The nozzle 25 is carried by a slide movable horizontally on the part 21 of the vertical slide 20, and this slide 22 is operated by a rod 40 and cam &c. to move the nozzle 25 inwards towards the nozzTe 30, buckling the sheet downwards on to the pile as at 12<b>, Fig. 7. The lifting and buckling movements raise the sheet as shown in Fig. 5, whereupon a pressing-foot 16, which has been previously lifted and moved outwards clear of the sheet, is moved down and inwards on to the pile under the lifted sheet. The nozzle 25 then moves outwards, away from the nozzle 30, to straighten the lifted sheet, and complete separation is assisted by a blast of air from the pressing-foot 16. In the modification shown in Fig. 9, the nozzle 30 is omitted, and the top sheet of the pile 12 is bent and buckled at 12<a> and 12<c> by the concave nozzle 25, which has the lifting and diagonal inward movement as in the arrangement described. A finger 68 over the corner of the pile limits upward lift of the sheet by the blast nozzles 13, 14. The nozzles 25, 30 are connected by pipes 26, 31 to a suitable vacuum device with valves for effecting the suction at the proper times.

Title: Trigger mechanism for automatic firearms
IPC: F41A19/31
Filed: 1950-06-02
Abstract: 672,103. Automatic firearms. VERWALTUNGSGES. DER WERKZEUGMASCHINENFABRIK OERLIKON. June 2, 1950. [June 4, 1949] No. 13907/50. Class 92 (ii). Means are provided in the mechanical chain of intermediate members for transmitting trigger movements to a sear, which at the beginning of the release movement of the trigger, interrupt this chain immediately in front of the sear thereby elminating the inertia effect of the chain and permitting the sear to return to its locking position at once. In the construction shown, the sear 8 engages a bent 7 of the breech-block 4, and carries a spring- pressed pawl 11 which engages a cam face 16 on the breech-block as in Specification 608,349 and serves, in the position shown, to hold the sear in the locking position. The pawl can be depressed to release the sear by trigger mechanism which includes a pull rod 18, levers 14, 17, on a shaft 15, a spring-pressed pawl 20 pivotally mounted at 21 and having a degree of lost motion at 24, 25, with an arm 37 on an arm 19 of the lever 17, and a spring-pressed catch 26 mounted in the breech casing. The pawl 20 is urged by its spring to engage a surface 23 on the arm 14. Thus on pulling rod 18 both levers will move clockwise against the action of their springs 33, 34, the lever 14 serving to act on the pawl 11 to release the breech-block during this movement. After this is done the pawl 20 engages and pushes back the catch 26 and then rides over it to reach the position above the catch as shown in Fig. 3. If now the trigger is slightly released the lever 17, 19 moves anticlockwise, and the catch 26 swings the pawl 20 clear of the surface 23, thus freeing the lever 14 to move alone to its normal position shown in Fig. 2. When the last round in the magazine 3 has been fired a follower 44 rocks a lever 40 to release a spring controlled rod 36 which engages and moves the arm 37 to release the pawl 20 from the lever 14. In a modification, Figs. 10 to 12 (not shown) a pivoted trigger acting on a pivoted sear which engages the breech block, is combined with means similar to the pawl 20 and catch 26 arrangement, but in this case the catch is pivoted.

Title: Improvements in or relating to the purification of naphthalene
IPC: C07C7/12
Filed: 1948-05-26
Abstract: Highly refined naphthalene having a minimum melting point of 79.6 DEG C., which has turned brown or tends to do so on storage is passed in the molten state through a layer of silica gel or of ferric oxide gel.  The preferred gel grain size is 30 to 100 mesh. Silica gel is preferably washed free from sulphate ion and heated to dryness before using it for the first time.  The adsorbent may be revivified by washing with alcohol, methanol or acetone and heating alternatively extracting with an inert solvent such as xylene or toluene before washing.  In an example, molten refined naphthalene is passed through a steam-jacketed column containing dried silica gel.  The product exhibits the fluorescence in ultra-violet light characteristic of naphthalene from which the tendency to turn brown has been removed. After 30 to 60 minutes the naphthalene supply is stopped, steam is blown through to displace the bulk of the hydrocarbon and the adsorbent is washed with methanol, residual methanol being displaced by warm air.  The column is then ready to treat more naphthalene. With naphthalene having a minimum melting point of 79.6 DEG  C. the cycle of operations can be continued for very long periods.

Abstract: 1431186 Controlling motor vehicles LABOBATOIRE D'ELECTRONIQUE ET D'AUTOMATIQUE DAUPHINOIS and F MAYER 23 March 1973 14256/73 Heading B7H [Also in Division G3] In a device, e.g. a motor vehicle, having one or more feedback loops by which functions are controlled in response to manual commands, a computer in the or each loop modifies the feedback signal according to the reaction of the human operator, as determined in an unspecified way from sensors influenced by the human reactions. As shown, a signal from a vehicle driver 13 actuated control member 20 is compared at 15 with a feedback signal from a transducer 24 coupled to a controlled element 23, modified at 13<SP>1</SP> which is said to be an "electronic image" of the driver formed by computer 12 in response to sensors 14 of the driver's reactions and/or parameters, and sensors 17 of parameters of the vehicle and/or external parameters. 16 is a store for the parameters; 13<SP>11</SP> is a fixed store of the driver's image and if 13<SP>11</SP> and 13<SP>1</SP> do not agree the system assumes it has the wrong driver and stops the vehicle. The effect of the modification of the feedback signal is to limit the response of the controlled member to a value which is "safe" for the vehicle and its driver. The operation may be modified by a manual adjuster 18, e.g. to give a "sporty" or "family driver" characteristic. 25 ... 28 are indicator outputs. Lists of the sensed factors are given; examples in group 14 are frequency and strength of control operations (driver reaction), pulse beat and encephalogram (driver parameters), and in group 17 state of the brakes and quality of the roads. None of the sensors or their signals are described. In Fig. 2 (not shown), operation of clutch, brake, acceleration and steering are monitored by transducers whose signals are proportional to the rate of change of the operation and are differentiated and filtered by a lowpass filter and combined by addition or multiplication by a device (44) whose output represents "driver's inadequacy" and is displayed on an indicator and provides the control. The rate of change of this signal (i.e. improving or "getting worse") is also displayed. In Fig. 3 (not shown), the output of this device is modified by a vehicle speed or engine power signal and divided by a signal derived from the steering movements. If the result is below a threshold value the fuel supply is cut off and warning lights operated.
